When Scooter cancels their number in order to get the homesick Kermitin front of an audience, Rick, the more lucid of the two, physically intimidates the go-fer; after all, the easily bewildered Leif (who doesn't realize they've left their nursing home) has been looking forward to the gig all week.

The Zimmer Twins are eventually allowed to (literally) crash Kermit's Koozebane sketch, landing a spaceship that was supposed to have housed the Poobs on, and consequently flattening, the Male and Female Koozebanian Creatures. Kermit predicts that this act will set off an intergalactic war.

The Zimmer Twins are a reference to Rolling Stones bandmates Mick Jagger and Keith Richards, popularly known as "Mick and Keef".
